To know your limits...

Forgive me for dropping a link. I'm on a dozen forums, and copying a post with a lot of photos between the applicable forums can be frustrating.

I sat down to work on the fundamentals of marksmanship. The gun in use, my Kimber 82G, target at 50yds.

Evan, thanks for a very fine post.
I've never seen that device on the end of the barrel.
Excellent shooting sir.

The general gist is to shoot five rounds at 0, 1,2,3,4,5,6,7,8,9.
Take your smallest group, and look to see which number above or below it is the closest to your smallest group. From there you've 25 clicks per hash mark. So if your smallest group is 3, but 2 was closer to the same size than 4 was, drop down to 2.5 and shoot another 5 shots. Compare that new group to the group shot at three. If three is still smaller, move up to 2.75 or 25 clicks.

It helps with the barrel's harmonic balance across a given ammo type, really ammo lot. Once you get to your smallest group, make a note of it. It will be repeatable across that lot of 22lr. I have not tuned the barrel to CCI standard yet. It was set up for Federal 711b, which I don't have any more ammo of. It usually groups five shots into a ragged hole that a number 2 pencil wouldn't fit through.

Small correction, the scale goes up to 5, not 10. I was tuning the rifle to CCI Standard just now. The best repeatable group was at 3.5, I am sure I could tune it further, likely 3.4 or so, but shooting endlessly for groups was boring.

So, I worked on clearing my smaller KYL target. I cleared it twice out of 6, first and fourth attempts. After that, I used the last 20 or so rounds to focus on delivering rounds to the 1/4 swinger plate.
